We use esxi that does not allow you to install anything on the hosts.
However, vmware does provide you wth a Perl-library
(http://www.vmware.com/support/developer/viperltoolkit/) so that you
can query your esx(i)-servers about load, network traffic, disk usage
etc. You query with the library, the virtualcenter server.
We made a Xymon check on the Xymon serer (very quick and dirty) but I
do have some graphs and info now that is very informative without
logging in into the vmware console. Just the normal, plain, very
informative XYmon, yahoo!

I saw a couple of threads on this topic from January and was wondering
if there is any newer insight into this question. At that time, it
appeared that many were just installing a RedHat based version of the
Xymon (hobbit) client (with modifications to the df [vdf] and top
[esxtop] commands) on their ESX servers despite the warning that it may
void your support. I have started down the SNMP monitoring path and
have found that most of the fields listed in VM's MIBs are not
populated. So, are people still running modified versions of the hobbit
client without issue? Has anyone made any real progress on monitoring
ESX servers via SNMP?
Because of the support issues with Xymon on the service console and the limitations of SNMP, we're looking to using a vMA as a proxy for the ESX hosts. It's early days yet, but it looks quite feasible.
